Frontal Fibrosing Alopecia (FFA): Tracking Hairline Recession

FFA Is a Scarring Alopecia That Causes Band-Like Frontal Hairline Recession

Frontal fibrosing alopecia (FFA) is a scarring alopecia that primarily affects postmenopausal women, causing a distinctive band-like recession of the frontal hairline. Unlike androgenetic alopecia, which miniaturizes follicles but leaves them capable of recovery, FFA permanently destroys follicles through lymphocytic inflammation. The condition has been increasingly recognized over the past two decades and appears to be growing in prevalence.

Because FFA causes irreversible hair loss, early detection and consistent tracking are essential for preserving as much hair as possible through timely treatment.

How FFA Differs from AGA

FFA and AGA both cause hairline recession, but the mechanisms, patterns, and treatment approaches are fundamentally different.

The Band-Like Recession Pattern

The most distinctive feature of FFA is the way the hairline recedes. Rather than forming the irregular "M-shape" of male AGA or the part widening of female AGA, FFA produces a uniform, band-like recession. The hairline pulls back evenly across the forehead, often leaving a strip of pale, smooth, scarred skin where hair used to grow.

In many patients, the recession extends to the temporal and preauricular (in front of the ear) areas, and sideburns are lost entirely.

Recognizing FFA: Key Signs

Primary Signs

• Uniform frontal hairline recession with a distinct border between hair-bearing and hair-free scalp
• Eyebrow thinning or loss (partial or complete), often preceding or accompanying scalp involvement
• Sideburn loss on one or both sides
• Perifollicular erythema (redness around individual hairs) at the active margin
• "Lonely hairs" remaining in the scarred zone (isolated retained hairs within otherwise bald areas)

Secondary Signs

• Facial vellus hair loss (fine hairs on the forehead and temples)
• Body hair loss (limbs, pubic area)
• Lichen planus pigmentosus (darkened patches on the face or neck) in some patients
• Scalp symptoms including itching, burning, or a sensation of tightness at the hairline

Tracking Protocol for FFA

Why Precision Matters

FFA can advance slowly (1-2mm per year in some patients) or more rapidly. Without precise measurements, it is easy to miss slow progression until significant hairline territory has been lost. Tracking provides the objective data needed to assess whether treatment is controlling the disease.

Step 1: Establish Measurement Landmarks

Choose fixed reference points for your hairline measurements:

• Glabella (the flat area between your eyebrows) to the center hairline
• Lateral canthus (outer corner of the eye) to the temporal hairline at a horizontal line
• Tragus (the small cartilage flap in front of the ear canal) to the sideburn/preauricular hairline

These anatomical landmarks do not change over time, making them reliable reference points for measuring recession.

Step 2: Monthly Photo Protocol

Take standardized photos at the following angles. Learn how to take hairline tracking photos for detailed positioning guidance.

Required angles:

1. Frontal, hair pulled back: Shows the full frontal hairline
2. Right temporal profile: Shows right sideburn and temporal hairline
3. Left temporal profile: Shows left sideburn and temporal hairline
4. Close-up of active margin: Shows perifollicular detail at the hairline edge

Photo conditions:

• Same lighting every session (natural daylight is most consistent)
• Hair pulled straight back from the forehead (dry hair, no product)
• Same distance from camera
• Same background

Step 3: Document the Active Margin

The active margin is where FFA is currently working. This is the zone at the edge of the hairline where inflammation meets healthy follicles. In tracking photos, look for:

• Redness around individual hairs (perifollicular erythema)
• Scaling or flaking at the base of hairs
• A "papule" or bump around individual follicles
• Progressive loss of fine vellus hairs just ahead of the main hairline

Understanding the difference between miniaturization (AGA) and scarring (FFA) helps you recognize what you are seeing at the active margin.

Step 4: Track Eyebrows and Body Hair

FFA commonly affects eyebrows, sometimes before scalp involvement becomes obvious. Monthly eyebrow photos (close-up, same lighting) can document thinning that might otherwise go unnoticed.

If you have body hair involvement, periodic photos of affected areas (arms, legs) add useful data points for your dermatologist.

Treatment Options

FFA treatment focuses on suppressing the inflammatory process to halt further follicle destruction. No current treatment reverses scarring that has already occurred.

Medical Treatments

• Hydroxychloroquine (200-400mg daily): An immunomodulator commonly used as first-line systemic therapy for FFA. Takes 3-6 months to assess effectiveness. Requires baseline and annual eye exams (rare risk of retinal toxicity).

• Finasteride (1mg-5mg daily): Used in postmenopausal women (off-label) to modulate the hormonal component of FFA. Some studies show benefit in slowing progression. Not appropriate for premenopausal women due to teratogenic risk.

• Doxycycline (100-200mg daily): Used for its anti-inflammatory properties. Often combined with other treatments.

• Topical tacrolimus (0.1%): A calcineurin inhibitor applied directly to the active margin. Reduces local inflammation without the skin-thinning effects of corticosteroids.

• Intralesional corticosteroids: Triamcinolone acetonide injected along the active margin every 4-8 weeks. Provides targeted anti-inflammatory effect.

• Topical or intralesional corticosteroids: For localized control of inflammation at the hairline margin.

Combination Approaches

Most dermatologists use combination therapy for FFA, such as hydroxychloroquine plus topical tacrolimus, or finasteride plus intralesional steroids. The specific combination depends on disease activity, patient factors, and treatment response tracked over time.

Surgical Considerations

Hair transplantation in FFA-affected areas is approached with extreme caution. Transplanted follicles can be attacked by the same inflammatory process. Some specialists attempt transplantation only after 2+ years of confirmed disease inactivity (tracked by stable hairline measurements and absence of symptoms). Results are less predictable than in AGA.

The Importance of Early Detection

FFA destroys follicles that cannot be replaced. The difference between starting treatment when you have lost 1 cm of hairline versus 3 cm represents a significant cosmetic impact and a much harder starting point for management. Every month of uncontrolled disease means additional permanent loss.

If you notice uniform hairline recession, eyebrow thinning, or any scalp symptoms at the hairline margin, seek dermatological evaluation promptly. A scalp biopsy at the active margin can confirm the diagnosis.
